 Update the README from the action file with https://github.com/npalm/action-docs `action-docs --update-readme`
-
-### Local testing
-
-To run and debug workflows from `testdata/example-*`, from
-the root of the source directory, with docker and forgejo-curl.sh
-installed, mimic what `.forgejo/workflows/integration.yml` does. There
-may be some manual tweaking (such as creating temporary directories)
-because the tests run as root, but they do not need to run as root.
-
-* `forgejo-curl.sh logout`
-* `forgejo.sh setup root admin1234 codeberg.org/forgejo/forgejo 1.21`
-* `firefox http://$(cat forgejo-ip):3000`
-* `forgejo-runner.sh setup`
-* `export example=pull-request`
-* `export EXAMPLE_DIR=$(pwd)/testdata/example-$example`
-* `$EXAMPLE_DIR/setup.sh` # if it exists
-* `$EXAMPLE_DIR/run.sh` or
-* `forgejo-test-helper.sh run_workflow testdata/example-$example http://root:admin1234@$(cat forgejo-ip):3000 root example-$example setup-forgejo $(cat forgejo-token)`
-* `forgejo-runner.sh teardown`
-* `forgejo.sh teardown`
-
-### Remote testing
-
-To reduce the runtime the following variables can be set to control
-the number of cases run by the
-[integration](.forgejo/workflows/integration.yml) tests. If set to
-**none** they are not run at all for that version of Forgejo. If
-it does not exist, all tests are run.
